Red deer are dark red or brown with a lighter color of cream on the underbelly, inner thighs and rump. There may also be some spots on the summer coats, particularly along the spine. In winter, the pelage changes to a darker brown or grey, with lighter patches on the rump and undersides. It is notable that their caudal patch tends to reach higher up the rump than is the case with other deer. Both sexes have tails of approximately 15 cm in length which are generally the same color as the caudal patch. This tail may have a dark dorsal stripe that can extend upwards along the spine. There is also a visible gland high on the cannon bones (the long bone immediately above the hoof) of the rear legs. Appearance can also be influenced by age and condition, for example yearlings and calves have a shorter head due to having fewer teeth in their jaw than an adult. Alternatively, when deer condition begins to fail through age their coats will often appear to be ginger in colour, even in the winter months.
